I have a site to prove what i said about Detonation and intake temperatures. These guys know what their talking about.

http://www.procharger.com/intercooled.shtml

This also proves that i can intercool my supercharger and run boost reliably on a 11.1:1 CR engine :P not much but enough

hcivic.com · 05-28-2003, 05:12 AM

to clear up those miscocceptions
turbos heat is a result of the air being compressed ie put your hand on your compressor its hot the exhaust is not the cause he cause is the compression of the air

JDMSpecAccordSir-T · 05-28-2003, 05:13 AM

And any one care to argue with this point

Quote:

5) This one is for all you traction guys who say a SC isnt good for traction. Duh cause it makes alot more power down low in the rpm range than turbo. Just put some slicks on and with a competent driver who can launch properly, a SC car with 12 psi would smoke a turbo car with 12 psi at the strip.

Im just using Psi as a reference. Substitute 12psi for, lets say, 250 peak whp.

JDMSpecAccordSir-T · 05-28-2003, 05:59 AM

Both SC and Turbo compress and therfore heat up air. My aruguement is that exhaust manifold heats up the compressor housing for the turbo ( being attached directly to the exhaust manifold). More heat than a centrifugical superchargers compressor housing (Vortech) being mounted elsewhere in the engine bay.

http://www.vortechsuperchargers.com/images...s_underhood.gif
the compressor is well away from the exhaust manifolds heat

unlike the turbo

its right next to it plus joined to it. remember under very hard running the exhaust manifold gets very very hot (like 800 degrees hot).

K2e2vin · 05-28-2003, 01:06 PM

yes but what i am saying is an intercooler would cool that down(the heated air). the sc still sees hot air from the exaust manifold, because of the way the engine is positioned, the air has to go around the engine, with the air carrying the heat from the manifold. but in all the sc would give you less heat and better response. i was just saying that between a intercooled/aftercooled sc and a intercooled turbo that air entering the intake manifold would be almost the same.

JDMSpecAccordSir-T · 05-28-2003, 01:31 PM

Ok but a intercooler only can cool the air BY XX degrees NOT TO XX degrees.so if it 240 degrees when it enters the intercooler and the intercooler then cools the air by (for arguements sake) 100 degrees then when the air exits it will be 140 degrees. Now start 300 degrees as you agreed with me that the turbo's air would probably be hotter to begin with.

See where im going????

The end result would be 200 degrees (turbo) vs 140 degrees (SC)

no...

an intercooler "tries" to cool it to ambient, or outside temp. how much it will cool the temp by is determined by the efficientcy(measured in %) of the intercooler.

JDMSpecAccordSir-T · 05-28-2003, 10:39 PM

No everheard about windchill factor lets say the air moving over the intercooler is 30 degrees. the air before the intercooler is lets say 240 degrees, the intercooler will ATTEMPT to cool the air FLOWING through it (remember now that the air doesnt sit in the intercooler it passes through at a very high speed and is only in the intercooler for a very short period of time) to temperature of the air flowing over the intercooler. so it only therefore cools the air flowing through the intercooler by X degrees. so if it cools the air by x degrees you would minus that from the number you started with(240-X=??) starting with a lower number would leave you with a lower number (Turbo vs SC). Again the Intercooler ATTEMPTS to cool the air. If it could cool the air to the temperature of the air flowing over it it would be 100% effecient. A intercooler has yet to reach that goal. I dont even think water to air has reached that yet.

you cant use a fixed number, a intercooler DOES NOT cool by a constant, X is a variable so you cant use a absolute number on any temp. the efficiency of the intercooler will determine how close it will get to the target degree temp. if the outside temp is 80degrees then it will try to cool it to 80 degrees. most air-air intercoolers have 70-75% efficiency;ex: i will use 80 as ambient, intercooler inlet temp= 280, then the air exiting the intercooler is 130, which is pretty good. now with a air/liquid intercooler, you can look for efficiency somewhere in the 80-90 area, some are higher. with 90% efficiency the air exiting intercooler would be around 100degrees. now i will use 330degree intercooler intake temp with 90% efficiency intercooler; the end product is 104 degrees. if you see the difference between the intercooler inlet and outlet temps you will see that the first one i used was cooled by 180 degrees and the second one was cooled by 220 degrees, which are different numbers at the same efficiency.

JDMSpecAccordSir-T · 05-29-2003, 05:27 PM

To me that sounds like BS. For one the faster you drive the colder the air gets (not ambient which is the temperature of the standing air) and the more effecient the intercooler. And then your telling me that for ex:

240 inlet temperature> -75% effeciency intercooler (which is variable depending on how fast your moving) and all other things being equal, you will end up with SAME OUTLET TEMPERATURE if you had started out with a 340 inlet temperature?? Cuz thats what you were saying in the other post and thats my whole arguement.

This one's for you

JDMSpecAccordSir-T · 05-29-2003, 05:38 PM

The only effeciency variable between two exact same intercoolers is the speed/temp of the air moving over them (with everything else being the same). In real world situation there would hundreds of variables. But in a lab/dyno setting where the airflow/ambient temp is controlled (where X is not a variable), a Centrifugical SC intercooled setup would have a definite advantage over a Turbo intercooler setup as for intake manifold temps.

K2e2vin · 05-29-2003, 06:28 PM

i am using air/iquid intercoolers as examples for the 90% b/c its more difficult to run a air/air on sc. the air/liquid dont require any air to go through any fins on the intercooler but have air going past heat exchanger, which is done by the radiator fan. the outlet temps are close enough. get it through your thick ass skull. you are pro-supercharger so just stick wit it, you wont listen to anything i say. the sc would have advantage in making full boost earlier; no real distinct advantages through air intake temps. you dont even understand you are even saying; the intercooler will cool it close to ambient from just about any temp(normally seen), sc or turbo. you are saying intercoolers cool the air by only a certain degree, which is wrong, and you try to state that since the sc has a lower compressor outlet temp it automatically gets much colder air and has good advantage over turbo by just air temp. i suggest you hit the books and learn something on thermodynamics.

liquid00meth · 05-29-2003, 10:43 PM

It's all up to you man, it's what you want for your car. Why even both making a case to modify your own car.... your the one who owns it. lol.

JDMSpecAccordSir-T · 05-29-2003, 11:48 PM

And i suppose you have a degree in it or something. I think you're just being ignorant and why will it be more difficult to intercool a Centrifugical Supercharger with a air to air intercooler? Cuz you have a lack of imagination and cuz they don't make a kit for it?? And i know how a water-air works.

And Ok in which scenario will the intercooler have a harder job to cool the air to ambient?

300 degrees to "ambient" or
200 degrees to "ambient"??

Its impossible for a intercooler to "work harder" so therefore under the same conditions the 200 degree inlet temp would be cooled closer to "ambient". Period.

So pop a pill, smoke a cig, drink a beer whatever the fuck you do to chill out because your case is still

Oh sorry i just noticed this.

Ok oh i see now. thanks for clearing that up for me. Now i know you're full of

K2e2vin · 05-30-2003, 04:48 PM

no intercoolers dont work harder, they constantly cool it to a certain temp--inlet temp= 300degrees but air cooling it is 80degrees; 200degree inlet air but still 80 degree air cooling it.

btw ive seen a centrifugal sc with an air/air intercooler; but the pipe has hard bends and travels a long distance to one side of the car to the other side; while the regular aftercooler(air/liquid) takes it straight to the manifold.

K2e2vin · 05-30-2003, 04:55 PM

i am ignorant but yet i am trying to expain this to you huh?

btw, you talk about i have no imagination, i guess yours got the best of you.

JDMSpecAccordSir-T · 05-31-2003, 12:43 AM

Okay ive noticed how you completly ignored my question. Let me try this again. In which case will the air be cooled closer to ambient? or will they both be the same temp. I just need to hear you say it one more time so i can write off whatever you say as

300 degrees to "ambient" or
200 degrees to "ambient"??

Which one will easier for the 80 degree air to TRY cool to 80 degrees

Remember that TRY is the key word here as the intercooler cannot cool it to 80 degrees for the short period of time the air is in the intercooler.

K2e2vin · 05-31-2003, 05:21 AM

i didnt realize you were acutally asking a question but rather trying to make the statement of an intercooler working hard.

the 200 degree intercooler would be closer to ambient, but not by a significant number to make a real difference. with an intercooler you can just eliminate manifold inlet temp factor and just put it as supercharger vs. turbo. seems like you would go centrifugal sc which has some advantages over turbo so then just go with centrifugal sc; its your car.

btw you should try working for Vortech b/c you are the biggest pro-centrifugal sc person ive seen.

JDMSpecAccordSir-T · 06-01-2003, 02:51 AM

Ok Thank You i hoped you'd admit that there is a difference although its probably bigger than you would care to say (say with a smaller/less effecient intercooler the difference would be compounded). I didnt mean to offend anyone but if i know im right i wont stop until i've proven that (ill stop now

).

4)There has to be a reason why all NHRA Top Fuel Drag cars went SC over turbo. Maybe because a SC has more low rpm boost, produces less heat and is just generally more effecient than turbos.

Sorry to jump in late here, but this is a bogus point. Turbos are against NHRA rules. The reason they all run SCs is they have too.

JDMSpecAccordSir-T · 06-01-2003, 11:10 PM

Yeah i know about the rules. But what i meant to get across is why they didnt use turbos in the first place.

lsvtec · 06-02-2003, 11:45 AM

Actually they did start experimenting with turbos in the ealry 80's, they had problems with boost management and fuel delivery toasting thier engines so the NHRA made turbos illegal. IMO the NHRA decided that turbos would give teams with more techinal saavy a distinct power advantage over those teams that did not know or want to find out how to manage a turbo'd powerplant.

jeryjohn · 05-24-2007, 07:48 AM

dood trust me i'm rebuilding my b16A2 vortech supercharged engine and there is no such thing as a bolt on kit my vortech kit was amazing when installed felt better than my friends h22turbo until it blew 3 pistons 1 melted the other 2 cracked, you need the whole thing the pressure riser or FMU sucks ass and is a bitch for tuning bcoz u only get very aproximate fueling, now i've bought Neptune RTP ecu je internals rods bearings etc, but there is only one question left ,do i need cylinder sleeves i'm not raising the boost over 12 psi ever so do i????? can any one factualy tell me plz, not just i think, or my friends.......

Look at the date...

SR20S13 · 05-24-2007, 01:44 PM

to bring this thread back from the dead, a centrifugical supercharger wont spool all that much faster if not slower then a small turbo. Becuase you still have the spin the supercharger to a certain rpm. But your torque curve will be flatter becuse it just keeps increasing boost but it wont give you low RPM power like you think. The thing i cant stand about superchargers are that you have to lose power before you make power.

Becuase you still have the spin the supercharger to a certain rpm. But your torque curve will be flatter becuse it just keeps increasing boost but it wont give you low RPM power like you think. The thing i cant stand about superchargers are that you have to lose power before you make power.
